Welcome and good luck, Thiru. One thing you'll have to get used to, though, is waiting for the Nitpicker to get back to you before you submit another assignment.
Don't worry, I think everyone does that the first time
When you get a "Nitpick" back, make any appropriate changes and send it back to the nitpicker directly. Keep repeating this process on 1A until you get the "OK" from the Nitpicker, and then you can submit 1B.
Just thought you'd like an idea of how it all works! Welcome and have fun!
